Hi Jeff and WeatherCat weather gadget collectors,
I can only check this forum only about once a day, so sorry but my replies will be slow at best. My "other problem" is taking more and more of my time . . . .

Yes Davis is more expensive but one of the main reasons for going with Davis is things like: you can adjust every instrument from the weather station and . . . . the vast majority of the time they are spot-on. Davis has been in the business for decades and have specialized in the University/Professional Weather Station market. Lots of station used by folks like the National Weather Service are Davis stations. For amateurs like us there are two benefits: very accurate instruments and very tough reliable and trouble-free equipment.
As noted, these units are pricey, but you can get the price way down if you shop at the right places. To do what you want, indeed you'll need a standard weather station setup (they come in assorted flavors - and price tags) then indeed you need some secondary instruments. To do that you'll need at least one secondary data transmitter. However, you might be able to get more than one probe connected to a single transmitter. I don't have the need so I haven't looked into this though.
Given the price, it is well worth investing some time designing and planning your system. There are some nice examples on the "sister" website to WeatherCat:
MacWeather.net. The link to user examples is:

Everybody must be on vacation these days. Lots of our regulars are missing. However, you might want to start up a new thread either here on on MacWeather (or both) if you would like to pick the brains of the weather station "gurus" around here. Another place to check out is
WXForum. It is a busy place, but
lots of good info there.
Hope that is some help!!
Cheers, Edouard
